Where is the air inlet adjustment of Yamaha 2-40 cylinder?

The intake of Yamaha 2-40 cylinder is adjusted in the engine compartment. After opening the engine cover, you can see the intake pipe, which is connected with the intake port. The intake pipe refers to the section of pipe where air enters from the air inlet, passes through the air filter and then enters each cylinder. It is the main intake pipe and the main intake pipe of the engine.

The intake pipe can be divided into vertical intake and rotary intake. The intake resistance of the vertical intake port is small, which is beneficial to the formation of high-speed vibration and improves the intake efficiency. Suitable for engines with high speed and strong performance. Rotary intake port can be beneficial to the generation of vortex during intake, improve the mixing degree of air and gasoline, and improve the combustion efficiency in the cylinder at low speed. Suitable for engines with strong low speed performance.

Intake principle of Yamaha 2-40 cylinder

The working principle of the engine air intake system is that when the engine is working, the driver controls the opening of the throttle valve through the accelerator pedal to change the air intake and adjust the engine speed. After the air entering the engine is filtered by the air cleaner to remove impurities such as dust, it flows through the air flow meter, enters the power room along the throttle passage, and is distributed to each cylinder through the intake manifold. When the engine is idling, part of the air bypasses the throttle valve and enters the cylinder through the additional air valve or idling regulating valve.
